This little one doesn't look like a Silver Laced Wyandotte...the comb looks more crown shaped than horseshoe....it might possibly be a Silver Penciled Sicilian Buttercup...hard to know at this point but in a few weeks if the comb becomes more crown like, you'll know.

not a Welsummer...facial coloring wrong...Welsummer is a true chipmunk with clear head triangle, eye liner (especially girls), and stripe down back...not mottling around eyes with a lot of white...see one of my Welsummer hatches below.

Since it is random special...they could be almost anything and a lot of chicks have similar patterns. I can say you don't have a Barred Rock or RIR in the bunch....and not likely to have an EE either as I don't see any beard/muff or green leg particularly (one might).
I'd have to see some...
